Xnaron Printable Magnetic u-joint option for Rostock Max

[Eaglezsoar]

Xnaron,

You wouldn't have a dxf file of the effector mount would you. I want to mill one out of aluminum instead of the printed parts. I drew one up base on your photos/stls but i dont think its correct.

If you are able to fabricate the effector from aluminum, I would be interested in two.
I would be interested in aluminum cheapskate mounts also.

Make sure you get a good connection with jb welding the 3mm cap screw to the ball bearing. I had one come off during a print. I had properly prepped the ball bearing and screw with acetone and cured under a lamp.

No damage, but a mess of a print. In repairing it, I was able to use 320 grit sandpaper to sand through or at least abrade the section of the chrome surface of the ball where the cap screw is attached. I am hoping that will make for a better connection.

Retraction nailed!

im gonna try without bending first, looks like there might be room.

It looks like the only problem would be if a cheapskate dropped below the effector, which shouldn't happen under normal use.

The ease of disassembling this set up provides is phenomenal. It is so much easier to disassemble the hot end and effector with it connected to magnets. I highly recommend this set up.

Thank you for this wonderful idea. Magnetic holders it is very cool!

Looking Good!

I have two 3d printers and both are down waiting on parts from china. Can anyone print a set of parts for the Xnaron system
in return for cash. I would need the effector, the cheapskate Ballends (3) and 12 of the boom ends. If you can help please
PM me.

You could free up some space to make the aluminum effector a bit smaller by rotating the inner hole circle 30 degrees.

I detect a VCarve Pro or Aspire user...

Funny because my artcam sensor is going off on that one.

Did you create your own effector model? Or did you modify xnaron's?

[noddynomolos]

Wow MRBLADE that is a thing of beauty!!! Well done! What size tap did you use? Would love a copy of the .stl

[mrblade]

I create my own effector model.

I use cylindrical tips for D10mm magnets and D10mm carbon tubes.
Screwed M4.

Flateric, the funny thing is that the guy that did most of the work on Artcam left and started Vectric and they produce VCarve Pro and Aspire. They bring Artcam quality to the table without having to pay Artcam prices for it.

I Just posted some pictures of one of my first prints with the new arms and j head, in the what are YOU making section...

I just wanted to pass along another source for the Neodymium magnets that wasn't ebay.

http://www.mcmaster.com/#rare-earth-magnets/=muhxh6

edit: they have crappy linking, for the ball magnets click 'the ultra-high-pull neodymium-iron-boron magnets' section, it has a plate for it's magnet.

Or I'm not used to linking from this site. alt link: http://www.mcmaster.com/#neodymium-iron-boron-magnets

I thought I'd try out a flat aluminum effector plate with the mag arms today.

Though close, it makes it within my work volume (-120 through 120mm) without the rod ends touching the 3mm cap screws the ball bearings are sitting on. Here is a shot at Y-120.

Now I've got some Z travel back.

looks good. I prefer this method over the original design for durability of the aluminum plate against heat.

I have found that heat was not an issue. If you are really concerned you can print it out of abs instead of pla.

Looks great! Have you made any prints yet? Any pics of the finished mod and prints you can post?

[Eaglezsoar]

For those of you who are running this system for your arms, what is the longest time you have run using the JB Weld
without any failures of the Epoxy? This is important now that we have seen some failures using the JB Weld.

[geneb]

I'm skeptical.

I know of at least four people with the Xnaron arms installed without any bonding failures. To me, one bonding failure doesn't mean there's something wrong with the adhesive.
